AIFF to MP3 Without Quality Loss

Converting AIFF to MP3 involves lossy compression. Some data will be discarded. Use a high bitrate to keep loss minimal and nearly inaudible.

AIFF (.aiff) · Max 20 MB

AIFF stores audio without any compression artifacts. MP3 uses perceptual coding to reduce file size. The encoder discards audio data it predicts you won't hear.

At 320kbps, most listeners can't distinguish MP3 from the lossless source in blind tests. Use the highest bitrate your use case allows.

AudioUtils lets you pick the output bitrate. Choose 320kbps for near-transparent quality. Choose 128kbps for smaller files when size matters more than fidelity.

Frequently Asked Questions

What is AIFF?

Audio Interchange File Format. Apple's version of WAV. It stores uncompressed audio with support for metadata and album art. Common in Mac audio production.

How much smaller will the MP3 be?

About 80% smaller. A 40MB AIFF file becomes roughly 7-8MB as a 320kbps MP3.

Should I use AIFF or WAV for production?

Either works. AIFF has slightly better metadata support on Mac. WAV is more universal. Both are uncompressed with identical audio quality.

Is AIFF the same as Apple Lossless (ALAC)?

No. AIFF is uncompressed (like WAV). ALAC is lossless compressed (like FLAC). ALAC files are smaller but both preserve full quality.

About AIFF

Apple's uncompressed format. Similar to WAV but with better metadata support. Used in professional Mac audio workflows.

About MP3

The most widely used audio format. Great compatibility, small file size. Ideal for music, podcasts, and general use.
